Aircraft rescue and firefighting (ARFF) vehicles are putting on muscle, often carrying bigger payloads than ever before; having more compartment storage space; and sporting larger, more powerful pumps and engines.
ARFF manufacturers have changed their rigs to help operators get to an incident quicker, have greater visibility at the scene, and be more precise in putting extinguishing agent in the proper place.
Matthew J. Reda, international ARFF product manager for E-ONE, says E-ONE recently brought out a new version of its Titan® 4×4 ARFF vehicle, which has a redesigned cockpit-style cab, expanded windshield and side glass area for improved visibility, new pump and engines, and expanded compartment space.
Reda says the new Titan cab and windshield slopes forward and sits lower on the body to achieve greater visibility for the driver and other occupants than found in previous models of the rig. “With the new windshield design, an average size operator in the driver’s seat can see as close as nine feet in front of him, an improvement over traditional windshield designs,” Reda points out. In addition, the top turret is positioned lower and out in front of the rig’s operator, so it’s not necessary to look at an upward angle to see where the water stream is being placed.
Reda says the cab interior redesign is “similar to a military Apache helicopter where all cockpit controls are located to the center and front and available to both occupants of the vehicle.” The driver can control the pump, all turrets and handlines, the engine, and all lighting using a multiplexed system controlled through a programmable touch screen.
The new Titan 4×4 has its compartment space increased to 360 cubic feet of usable space in eight compartments, and both the engine and the pump are different from the previous version. The new Titan 4×4 is powered by a Scania 670-horsepower (hp) Tier 4 diesel engine and a Twin Disc six-speed automatic transmission. The pump change was made to a Hale 8FG rated at 3,000 gallons per minute (gpm) at 165 pounds per square inch (psi), although the pump will provide greater gpm from a pressurized water source.
The Titan 4×4 has a 1,585-gallon water tank, a 225-gallon foam tank, and 500 pounds of dry chemical and can pump any mix and combination of those three products through its Akron HydroChem technology nozzles where dry chemical is encapsulated in the water stream, allowing the dry chemical to be propelled farther. Its standard roof turret is rated at 750 gpm and has a dual-flow capability dropping to 375 gpm. The bumper turret will flow 250 gpm or more.
Reda adds that E-ONE is developing its 6×6 ARFF rig to use a Scania 770-hp engine, the same transmission and pump as the Titan 4×4; to have 320 cubic feet of storage space, with a 3,170-gallon water tank; and to have a 445-gallon foam tank. The 6×6 will be introduced this year, heexpects.
